how to Clean up(destructor) a dynamic Array of pointers??
- by Ahmed Sharara
Is that Destructor is enough or do I have to iterate to delete the new nodes??
#include "stdafx.h"
#include<iostream>
using namespace std;
struct node{
int row;
int col;
int value;
node* next_in_row;
node* next_in_col;
};
class MultiLinkedListSparseArray {
private:
char *logfile;
node** rowPtr;
node** colPtr; // used in constructor
node* find_node(node* out);
node* ins_node(node* ins,int col);
node* in_node(node* ins,node* z);
node* get(node* in,int row,int col);
bool exist(node* so,int row,int col);
//add anything you need
public:
MultiLinkedListSparseArray(int rows, int cols);
~MultiLinkedListSparseArray();
void setCell(int row, int col, int value);
int getCell(int row, int col);
void display();
void log(char *s);
void dump();
};
MultiLinkedListSparseArray::MultiLinkedListSparseArray(int rows,int cols){
rowPtr=new node* [rows+1];
colPtr=new node* [cols+1];
for(int n=0;n<=rows;n++)
rowPtr[n]=NULL;
for(int i=0;i<=cols;i++)
colPtr[i]=NULL;
}
MultiLinkedListSparseArray::~MultiLinkedListSparseArray(){ // is that destructor enough??
cout<<"array is deleted"<<endl;
delete [] rowPtr;
delete [] colPtr;
}
